Refrigerated Freight Shipping: How It Works and What It Costs in 2026

Refrigerated freight shipping moves perishable or temperature-sensitive goods in an insulated trailer, called a reefer, with its own cooling unit that keeps the load at one agreed temperature for the whole trip. In late October 2026, DAT's national reefer spot rate averaged $3.63 a mile with fuel, about 56 cents more than a dry van.

That premium buys you a trailer that can keep lettuce at 34°F through a Texas afternoon or ice cream well below zero across three states. It also comes with rules a dry van load never has to think about: written temperatures, pre-cooling, airflow, and a federal food safety regulation that puts most of the responsibility on the shipper.

This guide covers how reefer shipping actually works, what it costs right now and why, what the FDA expects from you, and what the 2027 forecasts say. Every rate figure below is dated, because reefer pricing moves every week.

How Refrigerated Freight Shipping Works

A reefer looks like a dry van from the highway. The differences are inside the walls and on the front of the trailer.

The trailer and the unit

The walls, floor and roof are insulated, and a diesel-powered refrigeration unit sits on the nose. The unit can cool or heat, so the same trailer that carries frozen chicken in July can keep potatoes from freezing in a Minnesota January. The unit has its own fuel tank, separate from the truck's.

Insulation costs space and weight. A 53 foot reefer is shorter and narrower inside than a 53 foot dry van, and with the refrigeration unit on board it typically legally carries around 43,500 pounds of freight instead of the 44,000 to 45,000 a dry van can take. If you're planning pallet counts, our breakdown of how many pallets fit on a 53 foot trailer walks through the reefer math row by row. The short version: you can still get 26 standard pallets on, but only with one row turned.

A reefer holds temperature. It doesn't pull it down.

This is the single most misunderstood thing about refrigerated freight. The unit is built to remove the heat that leaks in through the walls and the heat that fresh produce gives off as it breathes. It is not built to chill warm product.

The University of Florida's revision of the USDA handbook on protecting perishable foods during transport is blunt about this. Apart from a few exceptions such as bananas, a trailer's unit isn't powerful enough to take the harvest warmth out of fresh produce, so your product needs to be at or close to its travel temperature before it goes on the truck. Load a warm pallet and the trailer will spend the whole trip losing that fight, and the receiver's probe will find it.

The trailer itself also needs to be pre-cooled to the setpoint before loading. The handbook notes that in hot weather this can take two hours or more, so build it into the pickup appointment instead of finding out at the dock.

Continuous or start-stop

Reefer units run in two basic modes. Continuous keeps the fans moving air through the load the whole trip. Start-stop (Thermo King calls it Cycle-Sentry) shuts the unit off once it reaches setpoint and restarts it when the box warms a few degrees. Start-stop saves fuel. Continuous holds a tighter temperature.

Fresh produce almost always rides on continuous, because it keeps generating heat and needs airflow to carry that heat away. Deep-frozen product that's well below freezing and tightly packed can often ride start-stop. If your product cares, put the mode in writing next to the temperature. A carrier won't guess in your favor.

Multi-temp trailers

Some reefers have movable bulkheads that split the box into two or three zones. The same UF handbook describes a typical three-zone setup: 0°F or below for frozen, about 35°F for chilled, and about 55°F for products that get damaged by cold. These work well for grocery and foodservice distribution with several stops. They're less common, so ask early if you need one.

Reefer Rates Per Mile in 2026: What Refrigerated Freight Costs

Here's where the national reefer market stood in the most recent full week of data, against dry van for comparison.

Sources: DAT Reefer Report, Oct. 26, 2026 and DAT's weekly national rates as reported by AJOT. These are averages of what brokers paid carriers on the spot market, not quotes for any one lane.

To put that in dollars: a 900 mile spot reefer load at the national all-in average would run about $3,267. Your lane could be well above or below that, because where the load picks up matters a lot.

Where you load changes the price

DAT also breaks reefer rates out by origin region. The spread in late October 2026 was enormous.

Loading a reefer out of the Upper Midwest cost about two and a half times what it cost out of Florida that week. That's the fall harvest at work. Potatoes, onions, apples and other late-season crops pull reefer trucks north, and FleetOwner reported outbound load-to-truck ratios in northern markets running two to three times their early summer levels this year. A very low outbound rate, like Florida's, usually means more trucks are sitting there than there are loads to haul out.

For shippers in the Chicago area and the rest of the Midwest, the practical point is simple: this fall has been an expensive time to ship refrigerated freight out of the region. If your volumes are flexible, moving some of them a few weeks earlier or later can save real money.

Why reefer costs more than dry van

The premium isn't arbitrary. A reefer carrier is burning extra diesel to run the unit, often for the entire trip and sometimes while the truck sits at a dock. The trailer costs more to buy, more to maintain, and carries less weight. The work is tighter too: appointment windows, pre-cooling time, washouts between loads, and claims exposure if the temperature drifts. And the reefer fleet is much smaller than the dry van fleet, so when produce season or a holiday push hits, there's less spare capacity to absorb it.

Charges to expect on top of linehaul

The fuel surcharge on a reefer load covers the truck's diesel, the same way it does on a dry van. Our guide to the fuel surcharge in trucking explains how it's calculated. Beyond that, the usual extras are detention when a driver waits past free time, lumper or unloading fees at grocery warehouses, extra stop charges on multi-drop loads, and occasionally a trailer washout. Detention matters more on reefer loads, because the unit keeps burning fuel the whole time the driver waits. Our accessorial charges guide covers how each one works and how to keep them off your invoice.

The Seasons That Move Reefer Rates

Reefer pricing follows the food calendar more than any other equipment type.

Spring and summer produce season. Harvest starts in the southern US and moves north through the summer. As it does, reefer carriers chase the high-paying produce loads, and capacity gets tight for everyone else, including shippers of frozen and packaged food who have nothing to do with produce.

Fall harvest in the north. As the table above shows, late-season crops from the Upper Midwest, Great Lakes and Pacific Northwest push northern outbound rates up through September and October.

Holiday food. Thanksgiving and year-end grocery demand add volume in November and December, just as winter weather starts slowing transit times.

DAT's 35-day forecast, published Oct. 26, has reefer spot linehaul edging up to about $2.78 a mile, with a forecast range of $2.70 to $2.86. DAT noted that reefer had the widest forecast range of the three equipment types, which is another way of saying it's the hardest to predict.

What the FDA Expects From Shippers

If you ship food that needs temperature control, the FDA's Sanitary Transportation rule applies to you. It's part of the Food Safety Modernization Act, and the operational part sits in 21 CFR 1.908. The key thing most shippers miss is that the rule puts primary responsibility on the shipper, not the carrier, unless a written agreement assigns duties to someone else.

The FDA's own definition of a shipper in its compliance guidance names "the manufacturer or a freight broker" as examples, meaning whoever arranges the transportation. That's one reason a good broker will ask you for your temperature in writing and send it to the carrier on the rate confirmation.

Here's how the rule splits the work, in plain terms.

Two points worth knowing:

A temperature recorder isn't automatically required. You'll see articles saying every reefer must carry one. The FDA's summary of changes in the final rule says the proposed requirement for a temperature recording device was replaced with a more flexible approach: shipper and carrier agree on how temperature is monitored, and the carrier has to demonstrate it held temperature only when asked. In practice, almost every modern reefer unit records data that can be downloaded, and you should ask for it in writing up front if you want it.

A temperature failure stops the sale. If anyone in the chain becomes aware of a possible temperature failure, that food has to be held back from sale until someone qualified judges that it's still safe. That's where most refrigerated freight disputes start, and it's why the paperwork matters.

The rule exempts businesses with under $500,000 in average annual revenue, along with a handful of other cases listed by the FDA. If you're close to that line, check the exemption list before assuming you're out.

Why it matters: according to the USDA Food Safety and Inspection Service, the range from 40°F to 140°F is the danger zone, where bacteria can double in about 20 minutes. A few hours with a failed unit can turn a full truckload of product into a total loss.

Reefer LTL, Partials and Other Options

Does reefer LTL exist? Yes, but it's a much smaller market than dry LTL. Fewer carriers run temperature-controlled LTL networks, coverage is more regional, and pricing is harder to compare. For a handful of pallets of chilled product, a reefer LTL carrier or a consolidated multi-stop truck can make sense.

Volume or partial truckloads. If you have too much for LTL but not enough to fill a trailer, a partial reefer load often beats LTL on handling and transit time, because your freight stays on one trailer instead of crossing docks. Every extra touch is a chance for the temperature to drift.

Full truckload. Most refrigerated freight moves as a dedicated full load. It's the cleanest option for temperature control: one shipper, one setpoint, no other freight opening the doors. You can see how we handle it on our full truckload service page.

Multi-temp or multi-stop. If you're supplying several stores or restaurants, a multi-temp trailer with planned stops can replace several separate shipments.

How to Book a Refrigerated Load Without Surprises

The FDA rule runs on written instructions, and so does every reefer dispute. Before you tender a load, have these ready:

Commodity and setpoint. What it is, the exact temperature, and an acceptable range if you have one. "Keep cold" isn't a setpoint.

Mode. Continuous or start-stop. If it's fresh, say continuous.

Pre-cool instructions. Trailer pre-cooled to setpoint before arrival, and your product at temperature before it's loaded.

Product temperature at pickup. Have the driver or your dock probe the product, and write the readings on the bill of lading along with the setpoint and mode. If something goes wrong later, that line on the BOL is the strongest evidence you'll have.

Loading pattern. Keep pallets off the walls where possible, don't block the air chute at the front, and leave room for air to return. The UF handbook calls inadequate air distribution a major cause of perishable losses, even in good trailers.

Appointments and dwell. Give real pickup and delivery windows. A reefer that waits six hours at a receiver is burning fuel and building detention.

Temperature data. If you want a download or live tracking, ask for it on the rate confirmation.

Carrier checks. A reefer carrier should have current authority, cargo insurance that actually covers refrigeration breakdown, and a clean record. Here's how freight brokers vet carriers before booking them. If something does arrive out of spec, our guide to freight claims covers the deadlines.

What 2027 Could Look Like for Reefer Rates

Nobody can promise where rates go next year, but the major forecasts published this fall point the same direction: higher, then steadier.

C.H. Robinson expects refrigerated truckload costs per mile to rise about 11% in 2027, after a forecast 31% increase in 2026, according to Truck News. Its reasoning is that trucking capacity keeps shrinking faster than freight demand grows, with the biggest year-over-year increases in the first half of 2027.

Arrive Logistics' 2027 forecast, also covered by Truck News, expects reefer spot rate growth to slow sharply into January and flatten in the second half of 2027, with contract rates holding up better. Its core point is that rates settle at a new, higher floor rather than falling back to the lows of the last cycle.

What that means if you ship refrigerated freight:

Expect a firm first half. Rates are forecast to be strongest early in 2027, and spring produce season lands in that window.

Look at contract pricing before spring. If you have steady lanes, locking rates before produce season usually beats chasing the spot market through it. Our spot vs contract rate guide explains the tradeoff.

Budget for a higher floor. The forecasts don't show rates returning to 2024 or 2025 levels. For background on why, see why truck freight rates are rising in 2026.

Refrigerated Freight Shipping FAQ

What is the going rate for refrigerated freight?

For the week ending Oct. 24, 2026, DAT's national average reefer spot rate was $3.63 a mile including fuel, or $2.73 a mile linehaul only. Rates out of the Upper Midwest were much higher and rates out of Florida much lower. Contract rates and your specific lane will differ.

Is refrigerated freight more expensive than dry van?

Yes. That same week, reefer ran about 56 cents a mile more than dry van with fuel, and 49 cents more on linehaul alone. The gap comes from reefer fuel, more expensive equipment, lower payload and a smaller fleet.

What temperature does a reefer trailer hold?

Whatever the shipper specifies. Frozen product usually rides at 0°F or below, chilled food around the mid 30s, and cold-sensitive produce such as bananas warmer still. The right number comes from your product, not the carrier.

Who is responsible if a load arrives too warm?

It depends on what was put in writing. Under the FDA rule, the shipper must specify the operating temperature, and a carrier that agreed to it must show it held that temperature if asked. A setpoint, mode and product temperature on the bill of lading are what settle most disputes.

Can I ship frozen and chilled products together?

Yes, in a multi-temp trailer with separate zones. Putting frozen and fresh product in a single-zone trailer at one setpoint usually damages one or the other.

The Bottom Line

Refrigerated freight shipping costs more than dry van, and in fall 2026 it costs a lot more than it did a year ago, especially out of the Midwest. Most of what goes wrong with it isn't the price. It's warm product loaded into a trailer that can't cool it, a setpoint nobody wrote down, or a mode nobody specified.
